READBACK (ADM1062/3/4/6/9)
The ADM1062/3/4/6/9 have an on- board, 12 bit ADC. A 12
channel mux (13 on the ADM1063) allows the ADC to measure the
voltage on the input pins, the temperature sensors (ADM1062/3)
and the auxiliary pins (ADM1066). The user can choose which
inputs the ADC reads by clicking the tick box of the desired input in
the readback window and can also choose to ‘read Once’ or
‘continuously read’ the voted in channels. As explained earlier the
software automatically detects the ADM106x device or devices on
the SMBus and configures the software accordingly. If an
ADM1062/3 is detected then the Readback window will display a
temperature graph as can be seen in figure 63.

Input Attenuation - Selecting ranges on the input channels
was discussed in the INPUTS section. By changing the range,
a different attenuation network is selected, thus scaling the
input voltage by a different factor. The scaling is done so that
the input can be compared to the an on- chip 1.2V reference.
The scaling is reported in the third column and shows the user
how the voltage is calculated. It also helps the user to
understand the code reported in the fourth column. This is
useful where the input voltage is a value which lies in the
overlap region between one range and another. Code in Hex-
This is a 12 bit hex version of the binary output from the ADC
Voltage/Temperature- This is the actual voltage/temperature
measured at the input. The software calculates the voltage in
the background, taking into consideration the attenuation factor.
The readback window also incorporates a temperature chart for
ADM1062 and 63 only
Continuous read/Averaging- A read is initiated in the software
by clicking <Read> . The user can then see the Code in Hex
and Voltage/temperature windows of the selected channels
updating. The user can choose to do a single shot read of the
selected channels or, by clicking in the <Continuous Read> tick
box, have the ADC cycle around each of the selected channels
until the <STOP> button is pressed.
If the user is concerned about noise on the input channel being
measured, the Averaging function can be turned on by clicking
the tick box. When enabled, the ADC will perform 16
consecutive measurements on a channel before returning the
mean average value of these measurements.
